======================================================================================================

 This script was tested with the following systems and browsers:

 - Windows XP: IE 6, NN 7, Opera 7 + 9, Firefox 2
 - Mac OS X:   IE 5, Safari 1

 If you use another browser or system, this script may not work for you - sorry.

------------------------------------------------------------------------------------------------------

 USAGE:

 Use the toolTip-function with mouse-over and mouse-out events (see example below).

 - To show a tooltip, use this syntax: toolTip(text, width in pixels, opacity in percent)
   Note: width and opacity are optional

 - To hide a tooltip, use this syntax: toolTip()

------------------------------------------------------------------------------------------------------

 EXAMPLE:

 <a href="#" onMouseOver="toolTip('Just a test', 150)" onMouseOut="toolTip()">some text here</a>
